Pha-2 won't work with Z walkman via. that ridiculous cable exclusively for F880 & ZX1. But you can use the 3.5mm to 3.5mm line out.
Can't believe Sony did not dac support wm-port with both pha1 & 2.Edited by AUDIOBREEDER - 1/28/15 at 7:48pm

Thanks for the info
spent time looking online before I posted,
been using Pha2 with my iPod and just was looking to compare it to the z walkman for fun
Do have any idea if .m4v files will play on zx1? can not seem to find an answer to that.

I don't have ZX1 as it didn't have much specs to warrant such a high price.
I don't think ZX1 natively will play apples .m4v unless one can download some media player via Google store that supports that file.
That's another thing I don't get. If one buys either movies from iTunes/microsoft, all players and phones that support video playback should do so.
Regarding z Walkman with pha2, you can also use one of those wmport to 3.5mm adapter.
I think also you can use the micro-hdmi to usb, but I don't know that works.
